java HttpURLConnection.setRequestMethod()不起作用 [英] java HttpURLConnection.setRequestMethod() doesn't work

问题描述

我想将请求方法从GET更改为POST.这是我的代码:

i want to change the request methodo from GET to POST. This is my code:

HttpURLConnection connection = null;  

     URL url = new URL("https://accounts.google.com/o/oauth2/token");

     connection = (HttpURLConnection) url.openConnection();
     connection.setRequestMethod("POST");
     connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
     connection.setUseCaches (false);
     connection.setDoInput(true);
     connection.setDoOutput(true);

但是如您在此图中看到的，在调试请求的方法时，它没有改变:

But as u see in this image while debugging the methodo of the request doesn't change:

推荐答案

那只是一个

That's just an implementation detail. The HttpsURLConnectionImpl object has a reference to a delegate, and sets that delegate's request method. If you expand the delegate field and check its method field, you'll see POST.

如果继续执行代码，您还将看到它尝试发送POST请求.

If you follow through with the code, you'll also see it attempts to send a POST request.
